Publication number: 20190328382Abstract: A suture construction and method for forming a suture construction is disclosed. The construction utilizes a suture having an enlarged central body portion defining a longitudinal passage. First and second ends of the suture are passed through first and second apertures associated with the longitudinal passage to form a pair of loops. Portions of the suture lay parallel to each other within the suture. Application of tension onto the suture construction causes constriction of the longitudinal passage, thus preventing relative motions of the captured portions of the suture.Type: ApplicationFiled: July 11, 2019Publication date: October 31, 2019Inventors: Kevin T.
